I am running php 4.4.7 as an apache module and am trying to upgrade to the latest version of php. I have already checked my file permissions and they are okay. Also, I have checked the changes between php 4 and 5 and they seem to not affect anything. When my host switches my site to php 5, the site goes completely blank. Thanks ahead of time for your help.
